I'm writing an essay for English class. I was just wondering if somebody could read over this sentence and tell me whether or not it sounds alright.

Everybody wants to be happy, but we often forget how easy it can be to attain hold of that happiness due to tragedies in our lives.

The word "attain" is the wrong word to use in this sentence.

You could change it to

". . . forget how easy it is to lose that happiness . . ."

Of course, I can help you with that! The sentence you provided could be improved for better clarity and coherence. Here's a suggested revision:

"Everybody wants to be happy, but we often overlook how attainable that happiness can be, especially when we face tragedies in our lives."

To check whether a sentence sounds correct, it is helpful to consider a few elements:

1. Grammar: Make sure the sentence follows the rules of grammar, such as subject-verb agreement and correct word usage.
2. Clarity: Ensure that the sentence expresses your intended meaning clearly and without ambiguity.
3. Coherence: Ensure that the sentence flows smoothly and logically within the context of your essay.

In this case, the revised sentence maintains the original meaning while improving the overall clarity and coherence. Remember to proofread your essay thoroughly for any other sentence-level issues and to ensure that your ideas are well-supported and organized.
